Abstract

A sectional box with corner forming and locking elements comprising a thermoformed plastics sheet element consisting of a central panel element of quadrilateral shape the sides of which are connected via preferential bending lines to four sides of lateral panel elements which can be bent over box-like on the central panel, in which on those sides extending from the corners of the central panel element, the lateral panel elements are provided with flanges which project outwards from the lateral panel elements and are in total mutually facing contact when the box is in its formed state. <IMAGE>

[Industrial applications]

 The present invention relates to a corner-mounted prefabricated box for forming and fixing parts. In the packaging and packing of fruits and vegetables, the container members used are of various types and shapes in the form of wooden or plastic boxes, and although they are sufficiently strong and low-priced, they are empty. Then there are problems in terms of transportation and restoration. These problems are more acute and costly and time consuming if they are to be collected in one place for transport or used in a remote location from the beginning. To eliminate these drawbacks, a prefabricated thermoformer that can be assembled and fixed in the assembled state with insertable pin parts in suitable thermoformed holes in the box part. A box of plastic sheets has been proposed. However, this system is rather complex to use and has placement and insertion issues during assembly.

The object of the invention is to solve the above-mentioned problems by means of a prefabricated box, which is likewise obtained by thermoforming of plastics, but which is very simple to build and assemble. A further object is to provide a box of the above type which is low cost and easy to transport in very small spaces. These objects are achieved in accordance with the present invention by an assembling box having corner forming and securing components, which is made of a thermoformed plastic sheet consisting of a square central panel member. The quadrilateral center panel member has its edges joined to the four edges of the side panel member via bendable lines, the side panels of which are boxed above the center panel. Is a prefabricated box that can be bent like the above, wherein the side panel member is formed by a flange on the edge extending from the corner of the central panel member, and the flange is the side panel. It is characterized in that it protrudes outward from the members, and the boxes as a whole are in contact with each other in the assembled state.

The structural and functional features and advantages of the prefabricated box of the present invention are illustrated by way of example and not limitation in the following specification with reference to the accompanying drawings. It will be clearer from the description of one embodiment. The figure shows parts of a thermoformed plastic sheet, generally designated by 10, which consist of several differently shaped panel parts joined together by joints.

The thermoformed part constitutes a plan view of a prefabricated box and consists of a square center panel member 11 and four side panel members 12 and 13, which in the example is a rectangle. , The panel members on the sides are the same and are arranged in pairs on the opposite side. These panel members consist, for example, of ribs, cutouts, and various holes that make them light and individually rigid. In addition, the weight-saving part allows the part of the material to be quickly repaired, the broken parts being returned to the production cycle and used to form other boxes, The substance is used to the maximum extent and optimally.

The center panel 11 and side panel components 12 and 13 are joined together by pliable lines 14 and 15, respectively, which lines are likewise formed by thermoforming. The four side panel parts 12 and 13 are bent and together with the central plate 11 form a box. They are formed with flanges 17 and 18 projecting outwardly from the side panel pieces on the lip extending from the corner 16 of the central panel 11. When the side panel parts 12 and 13 are bent with respect to the central panel 11 so that they lie on each other to form a box, these flanges assume a vertical position with respect to the horizontal central panel and are parallel. The parts are brought into contact with each other. When the flanges 17 and 18 contact each other as described above, they form an intermeshing and immobilization consisting of a column 19 having a central vertical slot 20 defined by two shaped vertical walls 21. It is plugged into the part. The shaped wall 21 extends from a region near the corner of the column 19 having a cross section in the form of an isosceles right triangle. The two walls 21 are held in place by a plurality of horizontal ribs 22 extending from a peripheral wall 23 defined by the equal edges or catheter portions of the isosceles triangle. At its lower end, this column is provided in a corresponding hole 25 provided almost near the corner of the center panel 11 and in a folded portion 27 similarly connected to the center panel 11 corresponding to the corner. It consists of a pair of vertical pin parts 24, which are inserted into the corresponding holes 26. The pin piece 24 and the holes 25 and 26 thus serve as a centering mechanism, as well as partially working together to secure the pieces together.

The prefabricated box of the present invention is quickly assembled by simply inserting the flanges 17 and 18 into the slots 20 in the four column parts 19 from a flat form of transport and storage position. By providing the unique shape of the slot 20 and the ribs 22 for anchoring on the column 19, the flanges 17 and 18 are plugged into them and compressed together, the flanges 17 and 18 are optimally fixed . If this box is used to put a product inside and transport it, it will be disassembled into flats and corner fittings again and it will be much easier to transport. In this regard, excellent storability with minimal size was achieved in a small space. On the other hand, if the box is not reused, instead of using corner fixing columns, if the flanges of the corners contact each other, they are joined together. FIG. 6 illustrates how two contacting flanges are welded together to form the box of the present invention.
